LUBHBYIOATINGFSYSTEM ro'R QUIL L NG Mecnmns Original application filed December patent for quilling ma- The object of this invention is 'to provide in a yarn-winding machine, asiaquilling machine, for the adequate lubrication of a moving system of parts including ;awind ing unit and its driving means, the construc-' tion being preferably such as to avoid escape of the lubricant to such exterior portions or surfaces of the machine'as there isocoasion or possibility for the material being Wound or the atte'ndants hands to touch.

particular machine which is shown' and def.-

scribed herein by way of example.

i dicated protrude) and having" a removable 1 Fig. 2. It may have alla'round a troughcover 2 partially shown by dotted lines in was like. flange or lip 3 7V to catch and confine V such oil as may work its way from the housing. The bottom of the housing has upstanding therefrom a continuous wall 5 forming (Fig. 3) an elongated well 6 open at the top,

and at both sides of this well a receiver 7 o (is formed whose bottom slopes toward one end of the housing, where it is suddenly depressed to form a sump, asat 8. The well; 6 is kept supplied with oil as I shall explain. later..

-'The main'horizontal shaftlO is journaled in a bearing 9 at one end of the housing and it and two rock-shafts 11, one each'side of i and "fed along the threadingofthe Shaft 10has fixed thereon spiralgears vention is not necessarily limited to the ffor'drivingjthewih ihg' l w Forthe present purposes it is unnecessary 1 to describe each-winding unitor mechanism for building the woundpackage, (A, Fig, '1 ,with more particularitythan as follows; p

.2; Each such unitincludesa spindle .35 and a thread-guide 36, the former rotating and-the latter in-the present example both reciprocat; ingand progressing relatively'to theformer onthe rod 37Iand havinga'fork'8604 engaged inthe peripheralfgroove of nut 38screwed on a reciprocated threaded traverse.-bar;39

Thespindlewhich is journaled in the opposite side 'og wq housing 1 and protrudes from one of them, has a spiral gear 40 thereon normally fixed thereto and meshing with one of the gears 33. The traverse-bar 39 is supported in that one of said walls of the housing from which the spindle protrudes and by a link 46 3) it is pivotally connected with a crank 47 on one of the rock-shafts ,11, normally fixed thereto. Thus when the shafts 10 and 11 are in motion, as described, the spindle is rotated from shaft 10 and the thread-guide reciprocated from a shaft 11 so that the building of the package will proceed as indicated.

The gears 40 of all the winding units dip into a body of oil B (in well 6) from which it is transmitted, by their rotation and consequent ejection action and largely by spraying, to the various bearings, as of the shafts l0 and 11, the spindles and the rods 39, the thus-ejected oil being of course confined in the housing. The level of the oil is maintained such that said gears 40 dip into the oil at constant depth at any speed of the machine by forming the well with an open top and providing, exterior of the well, a lubricant receiver, 7 (here formed all around the well and including the depression 8), arranged to receive substantially all vagrant lubricant discharged from the Well, and by also providing means (as will appear) which returns the oil from the receiver to the well at a faster rate than it is ejected from the well by said gears.

The means last mentioned here consists of an oil-conductor 58 in the form of an inclined chute secured by its bracket 59 to the inner web 15a of bridge-member 15 and having its upper edge formed to the same profile as that of and wiping against the inner face of cam 24, its inner end overhanging well 6. The cam 24, by dipping into the oil in the receiver (where it is preferably deepened, as at 8, in order to immerse this cam at adequate depths), in its rotation and by ad hesion of the oil thereto acts as an elevator, carrying the oil up and over to the chute 58, by which it is wiped off the adjoining face of the cam (and which acts as a wiper as well as a chute) and is delivered to the well 6, the rate of return of the oil to the well by this simple means being found in practice considerably to exceed that of its ejection therefrom.

By vagrant oil discharged from the well I mean to include what overflows the well and is ejected by the gears 40 and does not remain adhering to any surface within the housing.

Of course by providing an upstanding wall, 5, to form the well I bring, as it were,

the level of the oil therein up to the gears 40.

Having thus fully described my invention what I claim is: v v

The combination, with a supporting strucparts carried by said structure within the housing and including winding units arranged in a series extending lengthwise of the well and an elongated driving member therefor also extending lengthwise of the well, said member and each unit having coactive means to transmit motion from the former to the latter dipping into the lubricant in the well, and means to return to the well from the sump lubricant ejected from the well by said coactive means and draining to the sump down said inclined surface.

In testimony whereof I affix my signature.
